However, the existing LED screens still have certain defects in use, such as:

[0003] Patent application publication number CN218384401U discloses a mobile LED splicing screen. When the two sub-screens are unfolded to both sides of the main screen during use, one end of the clamping column is elastically matched with the movable hole, so that when the movable hole corresponds to the fixed hole, the other end of the clamping column is clamped with the fixed hole, so that the unfolded position of the sub-screen can be fixed without screws;

[0004] In the above-mentioned document, the LED splicing screen completes the expansion and splicing process of the screen body by adjusting the positional relationship between the main screen and the sub-screen during use. The LED splicing screen needs to be moved by rolling on moving wheels before use, and the lower end of the main screen is fixedly connected to the moving plate through a bracket. The outer side of the bracket is smooth and flat, and the bracket is composed of two groups of fixed rods, so that the height of the LED splicing screen is fixed during use, which is difficult to adapt to various situations.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In a specific embodiment, Figure 1-Figure 4 As shown, the problem that the existing LED screen is difficult to move by its own structure is solved;

[0032] A bottom plate 1 and a roller 2 fixedly mounted at the lower end of the bottom plate 1;

[0033] A support rod 3 is fixedly mounted on the upper end of the bottom plate 1 , and a lifting rod 4 is slidably mounted inside the support rod 3 , and a connecting plate 5 is fixedly mounted on the upper end of the lifting rod 4 , while a screen body 6 is fixedly mounted on the outer side of the connecting plate 5 .

[0034] When using the mobile LED screen, the LED screen can be moved to the desired position according to one's own needs. During this process, the LED screen needs to be pushed and moved by the lifting rod 4 or the fixed rod 7. During the movement, the roller 2 at the lower end of the base plate 1 needs to roll on the upper end of the ground to complete the movement of the LED screen. After the LED screen moves to the desired position, the pushing can be stopped. At this time, the LED screen can be stably docked at this position, thereby completing the movement process of the LED screen and effectively improving the convenience of the movement of the LED screen.

[0035] In one specific embodiment, Figure 1-Figure 6 As shown, the problem that the existing LED screen is difficult to quickly adjust the height is solved;

[0036] The lifting rod 4 is provided with a lifting structure inside, and the lifting structure can achieve the effect of quickly adjusting the screen body 6 to any height;

[0037] A fixed rod 7 and a sliding member 8 are provided inside the lifting structure. The fixed rod 7 is fixedly installed between the two sets of lifting rods 4, and the sliding member 8 is slidably installed inside the fixed rod 7, and a supporting spring 9 is sleeved on the outside of the sliding member 8. At the same time, two sets of pushing rods 10 are rotatably installed on the outside of the sliding member 8.

[0038] A moving groove 11 is provided inside the lifting rod 4, and a fixing block 12 is fixedly installed inside the moving groove 11, and a sliding rod 13 is slidably installed inside the fixing block 12, and the sliding rod 13 is rotatably connected to the end of the push rod 10 away from the sliding member 8;

[0039] A seal 15 is fixedly mounted on the outer side of the sliding rod 13 , and the seal 15 is in close contact with the moving groove 11 . A return spring 14 is sleeved on the outer side of the sliding rod 13 , and the return spring 14 is located between the seal 15 and the fixed block 12 .

[0040] After the mobile LED screen is moved to the required position, the height of the screen body 6 can be adjusted as needed. At this time, the fixing rod 7 needs to be pushed upward, and the upward movement of the fixing rod 7 will cause the lifting rod 4 and the screen body 6 to move upward synchronously. At this time, the air pressure between the support rod 3 and the lifting rod 4 is less than the external air pressure. At this time, the sealing member 15 will separate from the movement groove 11, so that the external air can enter the support rod 3 and the lifting rod 4. In this process, the sealing member 15 will squeeze the return spring 14 and make the return spring 14 shrink. After the screen body 6 moves to the required height, the fixing rod 7 is stopped from being pushed. At this time, the shrinking return spring 14 will expand and push the sealing member 15 to seal with the movement groove 11 again, so that the screen body 6 is limited to this height, thus completing the height adjustment process of the LED screen within a certain range, and effectively improving the convenience of height adjustment of the LED screen.

[0041] After the use of the LED screen is completed, it needs to be lowered to the initial position. At this time, it is necessary to press the sliding part 8 and make the sliding part 8 slide downward inside the fixed rod 7. During the downward movement of the sliding part 8, the supporting spring 9 will be squeezed and the supporting spring 9 will be contracted. The sliding part 8 will push the sliding rod 13 to move through the pushing rod 10. During the movement of the sliding rod 13, the sealing part 15 will be driven to move and the sealing part 15 will be separated from the moving groove 11, so as to facilitate the discharge of the gas inside the moving groove 11 and facilitate the downward movement of the lifting rod 4 inside the support rod 3. At this time, the use process of the LED screen is completed, which effectively improves the convenience of using the LED screen.

[0042] Based on the above embodiments, Figure 1-Figure 4 and Figure 7 As shown;

[0043] A limiting structure is arranged inside the bottom plate 1, and the limiting structure can realize the effect of automatic limiting of the LED screen;

[0044] A connecting rope 16 and a fixing frame 17 are provided inside the limiting structure. The connecting rope 16 is fixedly installed at the lower end of the fixing rod 7, and the fixing frame 17 is fixedly installed inside the bottom plate 1;

[0045] A rotating rod 18 is rotatably mounted on the upper end of the fixed frame 17, and a moving member 19 is rotatably mounted on the lower end of the rotating rod 18, and the moving member 19 is fixedly connected to an end of the connecting rope 16 away from the fixed rod 7;

[0046] A limit rod 20 is fixedly installed inside the fixed frame 17, and a lifting plate 21 is slidably installed on the outer side of the limit rod 20, and the lifting plate 21 is slidably connected to the moving part 19. At the same time, a strong spring 22 is sleeved on the outer side of the limit rod 20, and the strong spring 22 is located at the lower end of the lifting plate 21, and a contact plate 23 is fixedly installed at the lower end of the lifting plate 21, and a suction cup 24 is fixedly installed at the lower end of the contact plate 23 at an equal distance.

[0047] During the upward movement of the fixed rod 7, the fixed rod 7 will pull the moving part 19 to slide inside the lifting plate 21 through the connecting rope 16, and the sliding process of the moving part 19 will cause the rotating rod 18 to rotate, and the rotating rod 18 will cause the lifting plate 21 to slide downward on the outside of the limiting rod 20 through the moving part 19, and the lifting plate 21 will squeeze the strong spring 22 and cause the strong spring 22 to contract. During the downward sliding process of the lifting plate 21, the suction cup 24 will move downward through the contact plate 23, and the suction cup 24 can be made to contact the ground at this time, thereby increasing the friction between the lower end of the base plate 1 and the ground, ensuring the stability and safety of the LED screen when docked, and increasing the overall practicality.
